CLEANABLE HEAT-RADIATOR.

Application filed October 4, 1910, Serial No. 585,336.

To all whom it may concern:

Be it known that I, WILLIAM E. Bane, a citizen of the United States, residing at Lincoln, in the county of Lancaster, State of Nebraska, and whose post-office address is 1505 Tenth street northwest, \Vashington, District of Columbia, have invented certain new and useful Improvements in Clcanable Ilcatdiadiators, of which the following is a specification.

My primary object is to provide a device of simple and practical arrangement, de signed to receive from a stove or other source of supply and radiate the heat which ordinarily escapes into the outer atmosphere, through the tunnel or chimney.

A further object is to provide a radiator that i safe and easily constructed and of inexpensive material, easily obtained.

Another further object is to provide a radiator that is cleanable without disturbing any of its component parts, and without annoyance "from dirt, soot, smoke, or gas.

Still another object is to provide a radia tor with a revolving closure or head fitted with a cleaning device, whereby the interior of the tubes can be thoroughly and easily cleaned without the escape of smoke, soot or gas, and with no liability of breakage of parts.

Another object is to provide a radiator with a revolving closure, having a catch or ratchet to hold the closure in proper position for cleaning the tubes or pipes in the radiator.

With the foregoing and other objects in view, the invention consists in the novel arrangement, construction and combination of parts as will be hereinafter more fully described in detail, illustrated in the ac companying drawings and then claimcd.

Figure 1, is a view in side elevation of a heater constructed in accordance with my invention, showing what I term a single heater. Fig. 2, is a central vertical sectional view through one of the fines thereof and. the drums, the latter being broken away. Fig. 3, is a top plan view with the outlet pipe or thin'ible partly broken away. Fig. 41-, is a top plan view with the revoluble cap or end plate of the outlet drum removed. Fig. 5 is an enlarged fragmental sectional view of a part of the outlet drum, showing the manner in which the rotatable plate of said drum is secured and held against rotation.

The heater may be used either in a verti- Specification of Letters Patent.

cal position as shown in Fig. 1 or in a hori' zontal position, it. being understood that the devlce shown in F 1g. 1 may as readily be used in a horizontal position as in the vertical position shown.

As illustrated in Fig. 1, the device conr prises a plurality of tubes 10 which, at their ends, are connected to an inlet drmn 11 and an outlet drum 12 respectively. The inlet drum is provided with a thimblc 1 1, preferably placed in the outer end of the. drum as shown, and. the outlet drum 12 is likewise provided with a thin'lble 1:3 which is preferably placed in the side of the drum, these thimbles being provided so that; suitable connection 01? the heater with the heat supplying flue and the outlet or chimney may be made as will be readily undcrstmid.

The outlet drum 12 is provided at itsoutcr end with a ca p or closure plate 10 which is revoluble on the drum and capable of being held stationary in any adjusted position thereon. This cap or plate 16 is provided with an inwardly extending flange 17 which fits within the drum 12 as shown in full lines in Fig. 2 and in dotted lines in Fig. 1. The plate is provided with an opening 18 eccentric ot' the plate and which alincs with the lines 10 as the plate is revolved. This opening is normally closed by a closure-member 19 through which a cleaner rod 20 is extended, said rod being of su'flicient length to allow of the cleaner 21. carried thereby to lie within the drum 1.1 when the cleaner is not in use. On the outer end of the rod is a suitable handle 22.

h'lountcd in the inner end plate or head otthe drum 12 centrally thereof is a rod or post 2?) which extends through the revoluble plate 16 a suflicient distance to permit oi the mounting thereon of a swinging closure plate 2-1 employed in lieu oi the closure member 1!) when the latter along with the cleaner is removed. Also mounted on the extended end of the rod 22-) is an arm 2:") which, near its outer end, is provided with a pin 26 projecting downwardly through the plate 16 and engaging in one or another of a series of V-shaped notches 27 provided in the upper end of the drum 12. The arm 25 preferably made of spring metal and is also preferably extended a slight distance beyond the plate 16 as shown in Fig. 1, so that a finger catch is provided for lifting the outer end of the arm to disengage the pin from its notch, although ordinarily, such pin will ride out of its notch when the plate 16 is revolved due to the V-shape of the notches. It will be observed by reference to Fig. 1 that the flange 17 is of sufficient depth as to extend beyond the notches 27 so that no smoke or other products of combustion may escape at this point. The arm 25 turns with the plate 16, and since the inner end of such arm is raised some distance from the plate by reason of the mounting of the closure plate 24 on the same rod or post as the arm, the latter is oii'set near its outer end so as to bring such outer end down onto the plate, as clearly seen in Fig. 1. The arm 25 and plate 24: are held on the rod or post 23 as by a nut 28 or in any other suitable manner.

By means of a heater such as shown and described above in detail I am enabled to utilize the heat of the smoke and gas that is ordinarily Wasted, and derive therefrom suliicient heat for ordinary purposes, the heater being placed in a room or compartment and receiving the products of combustion given off from a stove or other form of heater in a separate room or compartment, thus heating the two rooms or compartment, from the one stove, furnace, or other source of heat supply.

The device is extremely simple, and comparatively inexpensive to manufacture, and while I have shown and described in detail a preferable embodiment thereof, it will be evident that various slight changes may be made in the details of construction without departing from the spirit or scope of the invention as claimed.

lVhat I claim is':

1. A heater for utilizing waste products of combustion, comprising an inlet and an outlet drum, heads on the inner ends 01": said drums, a plurality of tubes connecting said drums, the outlet drum provided with a plurality of notches in its outer end, a revoluble end plate on the outer end of said outlet drum having a flange fitting within the drum and projecting beyond said notches, a post carried by the inner head of said outlet drum and projecting through the revoluble end plate, an arm carried by said post and having a pin projecting through the plate to engage in said notches and hold the plate against turning, said plate provided with .an opening alming with the connecting tubes as the plate is revolved, a closuremember for said opening, and a cleaner carried by said closure member.

2. A heater for utilizing waste products of combustion comprising an inlet and an outlet drum, heads on the inner ends of said drums, a plurality of tubes connecting said drums, a post carried by the inner head of the outlet drum, a rotatable plate mounted on said post and constituting the outer head of said outlet drum, an arm mounted on said post and having a pin projecting through the rotatable plate and engaging the drum to hold the plate against rotation, and a cleaner carried by the rotatable plate.

3. A heater for utilizing waste products of combustion, comprising an inlet and an outlet drum, heads for the inner ends of said drums, tubes connecting said drums, a-rplate rotatable on the outer end of the outlet drum and constituting the outer head of said drum, said plate provlded wlth a cleaner opening eccentric of the plate, a post carried by the inner head of said drum and on which said rotatable plate is mounted for rotation,

means carried by said post and engaging the drum to hold the plate against rotation, and a swinging closure plate mounted on the post for said cleaner opening.

In witness whereof, I havehereunto set my hand and seal this 4th day of October 1910.
